Description

Technical Field

[0001] The present invention relates to the technical field of pole piece winding, and particularly to an upper winding machine structure. Background Art

[0002] During the pole piece winding process in battery production, the positive electrode, separator, and negative electrode are stacked in sequence and then rotationally wound into a battery cell structure, which is mainly used in the production of cylindrical batteries and some square batteries; the core of the pole piece winding process lies in the production and winding process of the pole piece, requiring process personnel to have rich experience and skills to ensure product quality and production efficiency. At the same time, attention should also be paid to safety issues during this process, such as preventing scratches on the pole piece.

[0003] Existing pole piece winding mechanisms are mainly divided into fully automatic and semi-automatic types. The equipment price of fully automatic winding mechanisms is high and not suitable for small and medium-sized enterprises. The semi-automatic pole piece winding machine mainly manually places the cut pole pieces into the corresponding slides, then presses the pole pieces and pushes them into the winding diaphragm box and winding needles. In the actual production process, the manual operation of the pole pieces into the winding diaphragm is inefficient, prone to problems such as pole piece deviation and dust falling on the pole pieces and being wound into the battery cell, and at the same time, the pole pieces are prone to scratching fingers. Summary of the Invention

[0004] The purpose of the present invention is to provide an upper winding machine structure to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An upper winding machine structure includes a winding machine body, on which two feeding boxes are fixedly arranged, and on the side walls of both feeding boxes, slides for pushing the pole pieces into the winding needles are fixedly arranged; a picking and placing mechanism, which includes two screws rotatably arranged on the winding machine body, on each screw, a threaded sleeve is threadedly connected, on each threaded sleeve, a sleeve is rotatably arranged, on both sides of each sleeve, a fixing plate is fixedly arranged, and on each fixing plate, a suction cup for adsorbing the pole piece is fixedly arranged; by rotating the screw, the threaded sleeve drives the sleeve and the suction cup to move above the feeding box, and at the same time, the rotation of the screw causes the suction cup to move downward to adsorb the pole piece, and then move again to place the pole piece on the slide, and after adsorbing the pole piece, the suction cup is shaken to prevent moving while carrying other pole pieces.

[0006] Preferably, on each fixing plate, an air suction pipe is slidably arranged, each suction cup is fixedly arranged at the bottom of each corresponding air suction pipe, and a first spring is fixedly arranged between each air suction pipe and each corresponding fixing plate.

[0007] Preferably, the picking and placing mechanism further includes a connecting plate. Each of the suction cups is fixedly arranged at both ends of each connecting plate. Each connecting plate is fixedly provided with an abutting rod, and an abutting plate is fixedly arranged on the outer peripheral surface of one end of the threaded sleeve close to the winding machine body.

[0008] Preferably, a plurality of abutting blocks are fixedly arranged at one end of the threaded sleeve close to the abutting plate.

[0009] Preferably, a support plate is fixedly arranged on the winding machine body. A first limiting rod and a second limiting rod are fixedly arranged at the bottom of the support plate. One end of each fixing plate far away from the screw rod is slidably provided with an anti-rotation rod, and each anti-rotation rod is fixedly connected to the winding machine body.

[0010] Preferably, a first inclined block is slidably arranged at one end of the first limiting rod close to the winding machine body, and a second inclined block is slidably arranged at one end of the second limiting rod far away from the winding machine body.

[0012] Preferably, a slider is slidably arranged on each of the sliding plates. A cylinder is fixedly arranged on each of the sliding plates, and each cylinder is fixedly connected to each of the sliders in a one-to-one correspondence. A flipping motor is fixedly arranged on each of the sliders, and a clamping plate is fixedly arranged at the output end of each flipping motor.

[0013] In the above technical solution, the present invention provides an upper winding machine structure, which has the following beneficial effects: the reciprocating movement of the screw rod driving the threaded sleeve can drive the suction cup to switch positions between the material discharging box and the sliding plate, so as to adsorb the pole piece from the material discharging box onto the sliding plate. The rotation of the screw rod can also control the rotation of the threaded sleeve, so that the abutting plate drives the suction cup to move down to adsorb the pole piece. At the same time, the abutting block makes the suction cup shake after adsorbing the pole piece, which can make only one pole piece adsorbed each time. The cooperation of the cylinder and the clamping plate can push the pole piece adsorbed on the sliding plate into the winding needle, thus realizing the automatic picking and placing of the pole piece, greatly improving the winding efficiency and reducing the cost.

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figure 1-8, An upper winding machine structure, including a winding machine body 1, two feeding boxes 2 are fixedly arranged on the winding machine body 1, and sliding plates 3 for pushing the pole pieces into the winding needle are fixedly arranged on the side walls of the two feeding boxes 2; a picking and placing mechanism, which includes two screw rods 21 rotatably arranged on the winding machine body 1, each screw rod 21 is threadedly connected with a threaded sleeve 22, and a sleeve 23 is rotatably arranged on each threaded sleeve 22, fixed plates 24 are fixedly arranged on both sides of each sleeve 23, and suction cups 27 for adsorbing the pole pieces are fixedly arranged on each fixed plate 24; rotating the screw rod 21 makes the threaded sleeve 22 drive the sleeve 23 and the suction cup 27 to move above the feeding box 2, and at the same time, the rotation of the screw rod 21 makes the suction cup 27 move down to adsorb the pole piece, and then move again to place the pole piece on the sliding plate 3, and shake the suction cup 27 after adsorbing the pole piece to prevent carrying other pole pieces from moving; the feeding box 2 is fixed on the side wall of the winding machine body 1, the feeding box 2, the sliding plate 3, and the picking and placing mechanism are all arranged in two, there is a certain angle between the two sliding plates 3, each feeding box 2 is parallel to the corresponding sliding plate 3, the two feeding boxes 2 respectively place the corresponding positive pole pieces and negative pole pieces, in the initial state, the threaded sleeve 22 is at one end of the screw thread groove of the screw rod 21 close to the winding machine body 1, at this time the picking and placing mechanism is above the corresponding feeding box 2, rotating the screw rod 21 forward drives the threaded sleeve 22 to rotate through the end of the screw thread groove at this time, when the threaded sleeve 22 rotates, it drives the suction cup 27 to move down, the suction cup 27 moves down to abut against the pole piece, when the suction cup 27 abuts against the pole piece, start the suction cup 27 to adsorb the pole piece, and then continue to drive the threaded sleeve 22 to rotate through the screw thread groove, when the threaded sleeve 22 rotates, it drives each suction cup 27 to shake up and down, so as to shake off the pole pieces under the picked-up pole piece, ensuring that only one pole piece is adsorbed and moved each time. After the pole piece is picked up, reverse the screw rod 21, at this time the threaded sleeve 22 moves upward above the sliding plate 3 along with the reverse rotation of the screw rod 21, when the pole piece picked up by the threaded sleeve 22 with the suction cup 27 moves to directly above the corresponding sliding plate 3, the threaded sleeve 22 moves to the end of the screw thread groove of the screw rod 21 far from the winding machine body 1, at this time reverse the screw rod 21, the screw rod 21 will drive the threaded sleeve 22 to reverse, when the threaded sleeve 22 reverses, it drives the suction cup 27 to move down again, when the suction cup 27 moves the pole piece close to the sliding plate 3, turn off the suction cup 27, at this time the pole piece moves onto the sliding plate 3, and then push the pole piece into the winding needle to complete the movement of the pole piece, which can effectively improve the winding efficiency of the pole piece.

[0027] Further, an air suction pipe 25 is slidably arranged on each fixed plate 24, each suction cup 27 is fixedly arranged at the bottom of each air suction pipe 25 in a one-to-one correspondence, and a first spring 26 is fixedly arranged between each air suction pipe 25 and each fixed plate 24 in a one-to-one correspondence; the tail of the air suction pipe 25 is communicated with an air suction pump, the air suction pipe 25 is communicated with the suction cup 27, when the suction cup 27 moves above the pole piece, push the suction cup 27 downward, and the first spring 26 stretches. When the suction cup 27 abuts against the pole piece, start the air suction pump to form an appropriate negative pressure in the suction cup 27, so as to suck up the pole piece, and then release the suction cup 27, and the first spring 26 makes the suction cup 27 lift up.

[0028] Specifically, the picking and placing mechanism further includes a connecting plate 28. Each suction cup 27 is fixedly arranged at both ends of each connecting plate 28 in a one-to-one correspondence. A butting rod 29 is fixedly arranged on each connecting plate 28. A butting plate 31 is fixedly arranged on the outer peripheral surface of one end of the threaded sleeve 22 close to the winding machine body 1. The suction pipe 25 is fixedly arranged at the end of the corresponding connecting plate 28. There is a suction pipe 25 and a suction cup 27 at the end of each connecting plate 28. When the suction cup 27 moves above the feeding box 2, the threaded sleeve 22 is driven to rotate by the end of the threaded groove. When the threaded sleeve 22 rotates, the butting plate 31 is driven to rotate. During the rotation of the butting plate 31, it abuts against the butting rod 29, so that the butting rod 29 moves downward, and then the connecting plate 28 drives the two suction cups 27 to move downward to abut against the pole piece. After the suction cup 27 abuts against the pole piece, the rotation of the threaded sleeve 22 stops. When the suction cup 27 adsorbs the pole piece, the threaded sleeve 22 is started again. At this time, the butting plate 31 is separated from the butting rod 29, and the suction cup 27 is driven to move upward by the first spring 26.

[0029] Furthermore, a plurality of butting blocks 32 are fixedly arranged at one end of the threaded sleeve 22 close to the butting plate 31. When the butting plate 31 presses down the butting rod 29 to make the suction cup 27 abut against the pole piece, the rotation of the threaded sleeve 22 stops. When the suction cup 27 adsorbs the pole piece and the threaded sleeve 22 is rotated again, as the threaded sleeve 22 rotates, the butting plate 31 is separated from the butting rod 29, and the suction cup 27 moves upward a certain distance. As the threaded sleeve 22 rotates, the butting block 32 abuts against the butting rod 29, and the butting rod 29 is driven to vibrate up and down by the triangular butting block 32, so as to prevent other pole pieces from being sucked up.

[0030] In another embodiment of the present invention: A support plate 33 is fixedly arranged on the winding machine body 1. A first limiting rod 34 and a second limiting rod 36 are fixedly arranged at the bottom of the support plate 33. An anti-rotation rod 39 is slidably arranged at one end of each fixing plate 24 away from the screw rod 21. Each anti-rotation rod 39 is fixedly connected to the winding machine body 1. The anti-rotation rod 39 can prevent the fixing plate 24 from rotating with the screw rod 21, so as to prevent the suction cup 27 from being deflected. When the screw rod 21 rotates forward and backward, the butting plate 31 is limited by the first limiting rod 34 and the second limiting rod 36, so that the screw rod 21 can drive the threaded sleeve 22 to move when rotating. In the initial state, the threaded sleeve 22 is at one end of the threaded groove of the screw rod 21 close to the winding machine body 1. At this time, the butting plate 31 is also close to the winding machine body 1. At this time, the butting plate 31 is separated from the second limiting rod 36, and the suction cup 27 is above the feeding box 2. At this time, the butting plate 31 faces upward, as Figure 6As shown in the figure, when the control screw 21 rotates clockwise, the thread sleeve 22 is driven to rotate clockwise through the end of the thread groove at this time. The thread sleeve 22 drives the abutting plate 31 to rotate clockwise. When the abutting plate 31 rotates clockwise, it abuts against the abutting rod 29, so that the suction cup 27 moves downward. After the abutting plate 31 separates from the abutting rod 29, the thread sleeve 22 continues to rotate clockwise. At this time, the abutting block 32 abuts against the abutting rod 29 and drives the connecting plate 28 and the suction cup 27 to vibrate up and down. When the thread sleeve 22 continues to rotate, the abutting plate 31 abuts against the first limiting rod 34 during the movement and pushes the first limiting rod 34 to retract. When the abutting plate 31 rotates clockwise for one week, the screw 21 is reversed. The screw 21 drives the abutting plate 31 to reverse. At this time, the abutting plate 31 abuts against the first limiting rod 34. When the screw 21 continues to reverse, the thread sleeve 22 moves away from the winding machine body 1 under the limitation of the first limiting rod 34. When the thread sleeve 22 moves to the end of the screw 21's thread groove away from the winding machine body 1, the thread sleeve 22 separates from the first limiting rod 34. At this time, the thread sleeve 22 is driven to rotate counterclockwise through the end of the screw 21's thread groove. The abutting plate 31 abuts against the abutting rod 29, so as to drive the suction cup 27 to move downward. When the suction cup 27 drives the pole piece to move downward to the slide plate 3, the rotation of the screw 21 is stopped, the suction pump is turned off, and the suction cup 27 places the pole piece on the slide plate 3. Then the screw 21 is rotated counterclockwise again, and the thread sleeve 22 rotates again. During the rotation of the thread sleeve 22, it abuts against the end of the second limiting rod 36 away from the winding machine body 1 and makes the second limiting rod 36 retract. When the abutting plate 31 rotates for one week, the screw 21 is rotated clockwise again. At this time, the abutting plate 31 abuts against the second limiting rod 36. Under the limitation of the second limiting rod 36, the thread sleeve 22 moves toward the winding machine body 1, so as to suck up the pole piece in the feeding box 2 again and prevent it from reaching the slide plate 3.

[0031] Specifically, a first inclined block 35 is slidably arranged at one end of the first limiting rod 34 close to the winding machine body 1, and second inclined blocks 37 are slidably arranged at both ends of the second limiting rod 36 away from the winding machine body 1. Second springs 38 are fixedly arranged on both the first inclined block 35 and the second inclined block 37; The sides of the first inclined block 35 and the second inclined block 37 away from the abutting plate 31 are arranged as inclined surfaces. One end of the second spring 38 on the first inclined block 35 away from the winding machine body 1 is fixedly connected to the first limiting rod 34, and one end of the second spring 38 on the second inclined block 37 close to the winding machine body 1 is fixedly connected to the second limiting rod 36; As Figure 6As shown in the figure, when the abutting plate 31 is in a position close to the winding machine body 1, rotate the abutting plate 31 clockwise. During the rotation of the abutting plate 31, it abuts against the first inclined block 35 and pushes the first inclined block 35 to move away from the winding machine body 1. After the abutting rod 29 rotates one circle, rotate the screw rod 21 counterclockwise. At this time, although the abutting plate 31 abuts against the first inclined block 35, the first inclined block 35 will not move, thus causing the threaded sleeve 22 to move away from the winding machine body 1. Similarly, when the abutting plate 31 moves to the side away from the winding machine body 1, rotate the abutting plate 31 counterclockwise. When the abutting plate 31 abuts against the second inclined block 37, it pushes the second inclined block 37 to move. Then rotate the screw rod 21 clockwise. When the abutting plate 31 abuts against the second inclined block 37, the threaded sleeve 22 moves toward the winding machine body 1. The reset of the first inclined block 35 and the second inclined block 37 is controlled by the second spring 38.

[0032] In another embodiment of the present invention: a top plate 15 is slidably arranged in each material feeding box 2, and an electric push rod 14 is fixedly arranged in each material feeding box 2. Each electric push rod 14 is fixedly connected to the corresponding top plate 15 in a one-to-one correspondence; there are two electric push rods 14 in each material feeding box 2, and the jacking ends of each electric push rod 14 are fixedly connected to the corresponding top plate 15. The pole piece is placed on the top plate 15. When the suction cup 27 takes away the pole piece each time, by controlling the electric push rod 14 to move up a distance equal to the thickness of the pole piece, the uppermost clamping piece can always be kept at the same height, which is convenient for the suction cup 27 to suck.

[0033] Specifically, a slider 10 is slidably arranged on each slide plate 3, and a cylinder 11 is fixedly arranged on each slide plate 3. Each cylinder 11 is fixedly connected to the corresponding slider 10 in a one-to-one correspondence. A turning motor 12 is fixedly arranged on each slider 10, and a clamping plate 13 is fixedly arranged at the output end of each turning motor 12; in the initial state, the slider 10 is in the middle position of the slide plate 3. When the pole piece is placed on the slide plate 3, a part of it is on the slide plate 3. At this time, start the turning motor 12, and the turning motor 12 drives the clamping plate 13 to rotate, so that the clamping plate 13 clamps and fixes part of the pole piece on the slider 10. At this time, start the cylinder 11, and the cylinder 11 drives the slider 10 and the pole piece to move toward the winding needle, so as to push the corresponding pole piece onto the winding needle for subsequent winding. Then the cylinder 11 resets. Two servo motors 4 are fixedly arranged inside the winding machine body 1, and the output ends of the two servo motors 4 are fixedly connected to the two screw rods 21 in a one-to-one correspondence. By controlling the positive and negative rotation of the screw rod 21 through the servo motor 4, the turning motor 12 can also perform positive and negative rotation.

[0034] Only certain exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
